Antumbris

• Walk with WASD or the arrow keys, drag to look, and hold Shift to run. On a phone, the stick bottom-left walks and a drag anywhere else looks; the run button toggles running.
• E (or Enter) acts: take ore, bank it at the shelter, pick up a droblet, set it down or save it at its den, board the ship. On a phone, the act button names what it will do.
• Space jumps, and held in the air it burns the jetpack. On a phone, the jump button does both.
• C (or the Menu button) opens the suit's upgrades, where the number keys buy.

Antumbris runs on AEON3D, the engine built here, with no third-party engine or library and nothing to install. The moon keeps one face to its sun, so sunlight is the only warmth and the ore you carry is weight. Four eclipses cross its morning. Bank twelve loads of ore to fuel the ship before the dark wins, then fly it to the planet that hangs overhead, find its eighteen droblets in their six coats, and carry them home one at a time.
